👉 In mathematics, a predegenerate algebra is an algebra that has at least one nonzero element but no multiplicative inverse. This means that for every nonzero element \(a\) in the algebra, there exists an invertible element \(b\) such that \(ab = 1\). In other words, there are no elements \(x\) and \(y\) with \(\frac{1}{x} = y\) and \(\frac{1}{y} = x\), which is a
